I find it interesting that it says to do the seam welding after the cage goes in (guessing to minimize any twisting issues). I've always had it in my head that its the other way around, but they have a bolt in cage . How did they ever survivie...

Any thoughts on that order? Seems like it would be easier on a bare car to seam weld it, I'd think the cage would make the sills on the WRX a little hard to get to, not to mention the jungle gym behind the seats.
